Answer:
Let the width of the Rectangle be x inches
Then, length is (3x-5) inches
Perimeter of the Rectangle= 46 inches (given)
According to the above problem,
Equation :---- Perimeter=2(length+breadth)
2{(3x-5)+x}=46
2(4x-5)=46
(4x-5)=46/2=23
4x=(23+5)=28
x=28/4
x=7
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches
Answer:
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches

z = 106
y = 74
Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.

Mary earned 24 points on her science test. The total points on the test was 30 points. What is Mary’s test score as a percent? Show work
Answer:
80%
Step-by-step explanation:
24 devided by 30 = 0.8
0.8 times 100 = 80%
Answer:
80%
Step-by-step explanation:
take the number you got and divide it by how many it was out of and then move the decimal two points to the right. 24/30= 0.8 then move the decimal and get 80 and add the percent sign.

Step-by-step explanation:
I don't understand this, I have the answer but I don't know or how to explain my work.
Answer:
B
Step-by-step explanation:
0.25 = 1/4 = 5/20
0.35 = 35/100 = 7/20
5/20 + 7/20 = 12/20 = 6/10 = 3/5
Answer:
Step-by-step explanation:
so first you would do 0.25+0.35= 0.6
now put 0.6 into a fraction= 6/10 because 6 is in the 10th place then simplify 6/10=3/5 which to find that you divide each side by 2

Does bin width matter when it comes to histograms? Why or why not?
Answer:
Avoid histograms with small bin widths that group data into lots of bins. A histogram constructed with small bin widths will show the distribution as a “pancake.” so no it does not help us see the pattern in the data.

If the zeros of a quadratic function are 3 and 8, what are the factors of the function?
ΟΑ.
(X + 8) and (x - 3)
OB.
(x - 8) and (x + 3)
O C.
(X + 8) and (x + 3)
OD.
(x - 8) and (x-3)
Answer:
OD
Step-by-step explanation:
The zero x=8 will make the factor (x-8) = 0 and the zero x=3 will make the factor (x-3) = 0.
so it's (x-8) and (x-3)

An intercepted arc has a length of 19 yards. If the radius is 4 yards, find the measure of the central angle in radians and degrees.
The length of an arc is the distance between the endpoints of the arc.
The central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]
The given parameters are:
[tex]\mathbf{l = 19yd}[/tex] --- length of the arc
[tex]\mathbf{r = 4}[/tex] -- radius of the circle
The length of an arc is calculated as:
[tex]\mathbf{l =r\theta}[/tex]
Divide both sides by r
[tex]\mathbf{\theta = \frac lr}[/tex]
Substitute known values
[tex]\mathbf{\theta = \frac{19}4}[/tex]
[tex]\mathbf{\theta = 4.75\ radians}[/tex]
Convert to degrees as follows:
[tex]\mathbf{\theta = 4.75 \times \frac{180}{\pi}}[/tex]
[tex]\mathbf{\theta = 4.75 \times \frac{180}{3.142}}[/tex]
[tex]\mathbf{\theta = 272.16^o}[/tex]
Hence, the central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]

Answer: x = 8/4 = 2
12(2) + 4(6) = 24 + 24 = 48 = 6*8
Step-by-step explanation:
$12X + $6(4) = (X+4)*$8
12X + 24 = 8(x+4)
12x + 24 = 8x + 32
12x + 24 - 8x - 32 = 0
4x - 8 = 0
4x = 8
x = 8/4 = 2

Answer:
C
Step-by-step explanation:
The 2 triangles are similar (AA postulate ), thus the ratios of corresponding sides are equal, that is
[tex]\frac{14}{2}[/tex] = [tex]\frac{49}{x}[/tex] ( cross- multiply )
14x = 98 ( divide both sides by 14 )
